Proposal
I love mango's, but the taste of it depends on the ripeness of the fruit. I have always wondered what the difference in time would be in how long it takes to ripen depending on whether I keep the mango in the fridge or out on the table at room temperature. I have a feeling that the time will be shorter for the room temperature, but it will be interesting to see the difference in days.
Therefore, I am going to see how long it takes for a mango to ripen at room temperature compared to how long it takes for a mango to ripen in the refrigerator.


The Experiment
First, let me explain to you what kind of mangoes I used, because there are many different kinds. For this experiment, I used Kent mangoes, which are a greenish, reddish yellowish color. They are very juicy and have a soft tender texture to them once they are ripe. It was important that I used all the same kind of mango, because otherwise this could have effected my data. After this experiment, I think I'll take a break on eating mangoes! I then placed a sticky label on each mango to ensure I could watch each one and how long it was taking it to ripen depending on where it was placed.


Below is a table of the data I collected for this experiment

Let me explain the table a bit, the temperature of 51 degrees would be the mangoes that were placed in the refrigerator, while the temperatures of about 73 degrees where placed in the back room by my porch where it's a bit cooler than the 75-76 degrees where the rest of the mangoes were placed in my kitchen.

Temperature # of Days
Mean: 62.5 Mean: 5.96
Median: 73 Median: 7
Standard Deviation: 11.74 Standard Deviation: 2.73
The Correlation coefficient = -.96419

I'm a little upset with how my scatterplot looks, but I can't change it because this is what my data is!



Conclusion:
After performing this experiment, it is obvious that leaving mangoes out at room temperature will ripen them faster than in the refrigerator. I have also learned that leaving them in the refrigerator doesn't ripen them correctly and leaves them with a different taste. I'm not happy with how my scatterplot came out but it's because of the data. If there had been more fluctuation in the temperature, the plot would have been spread out more, but since the temperatures in my home are pretty steady, especially the refrigerator because it's regulated, the temps were all about the same.

Looking at the data, there is one mango that took 10 days to ripen at the colder temperature, It kind of stands out from the other. I think the factor that explains this is how ripe it was before it went in. I tried to ensure that all mangoes were relatively equal in firmness when purchased, but that is kind of hard when you are buying as many as I needed! Let me tell you what, I'm all mangoed out for now!
